FLOOR-PLATE.

Specification of Letters Patent.

Patented J an. 5, 1915.

Application filed January 30, 1914. Serial No. 815,344.

To all whom it may concern:

Be it known that 1, CHARLES FRANKLIN CHRISTIAN, a citizen of the UnitedStates, residing at New York city, in the county and State of New York,have invented new and useful Improvements in Floor-Plates, of which thefollowing is a specification.

My invention relates to floor platesthat is, to plates used inconnection with steam pipes or pipes of other kinds, at the points wherethe pipes extend through the floor or through the ceiling or a wall asthe case may be, for the purpose of preventing direct engagement betweenthe pipe and the member through which the pipe extends.

My invention, while admitting of general use and adapted for variouspurposes, is of special value in the case of steam pipes extendingthrough ceilings and floors.

More particularly stated, my invention comprehends a floor plate made inhalves, each half having the general form of a semi-ring, the two halvesbeing provided with means for locking them together and holding themwhen thus locked, the semiring being further provided with means fordetachably holding it upon the pipe independently of any other part, andin such manner that, by separating the two halves of the ring, it may beinstantly disconnected from the pipe.

My invention further contemplates the use in connection with thesemi-rings, of spring fingers having such form and so located as toprevent the floor plate, after being placed in position upon the pipe,from creeping in the general direction of the length of the pipe, owingto expansion and contraction of the pipe due to changes in itstemperature.

Reference is made to the accompanying drawing forming a part of thisspecification, and in which like letters indicate like parts.

Figure 1 is a perspective, showing my device as employed in two separaterelations that is, in connection with afloor and in connection with aceiling. Fig. 2 is a perspective, showing the two halves of the floorplate as separated from each other.

Two semi-rings 3, exactly alike, are each provided with a substantiallysemicircular outer flange 4, and a substantially semicircular innerflange 5. Each of the semirings 3 is further provided with two lockingplates 6 and 8, which extend flush with the outer or free edges of theflanges 4: and 5. The locking plate 6 is provided with a slot 7, and thelocking plate 8 carries a V-spring 9 made in this instance of a' singlepiece of spring wire, and bent at 10 so as to form a notch.

The V-spring 9 of each semi-ring 3 mates a slot 7 of the oppositesemi-ring in such manner that when the two semi-rings are brought intoregistry, each V-spring 9 readily enters the slot 7 mating it, and whenthis is done, if the two semi-rings be forcedtoward each other, the bentportions or notches 10 of the V-springs, by engaging the adjacentportion of the locking plate 6, securely hold the semi-rings together,as shown in Fig. 1. Each semi-ring is further provided with two springfingers lll2, carried by the flange 5, and extending slightly oblique inrelation to the geometrical axis of the semi-ring. Moreover the springfingers 11 and 12 are bent slightly toward said axis, or in other words,they converge to some exten l/Vhen the two semi-rings are fitted arounda pipe 13 and secured together as above described, and as indicated inFig. 1, the spring fingers 11, 12, press firmly against the pipe, andthus secure the floor plate thereupon. In order to remove the floorplate from the pipe, the two semi-rings are simply pulled apart by hand.

The construction above described admits of the device being made easilyand cheaply. All parts of each semi-ring except the spring 9, beingintegral, can be stamped, struck up, or drop forged, and thus easilyformed. Again, if desired, they can be readily cast, or worked up invarious ways from scrap material. The V-springs 9, owing to their simpleform, can be rapidly formed one after the other in succession, from asingle wire. The V-springs may be secured to the semi-rings by welding,brazing, soldering or by any other approved means for securing a smallbit of metal to a larger body thereof.

The device, when complete and in position, presents a neat appearanceand is not liable to get out of order. Either of the semi-rings may beremoved and replaced independently of the other. That is to say, eithersemi-ring may be removed, and the remaining semi-ring will remainself-supported upon the pipe. This is because the spring fingers of eachsemi-ring are disposed substantially at opposite ends of a linerepresenting the general maximum diameter of the pipe. the springfingers thus located, the tendency of the floor plate to creep, in thegeneral direction of the length of the pipe, owing to expansion andcontraction of the pipe in consequence of changes in itstemperature, iscompletely avoided. The result is that my floor plate, being securedupon a pipe, will remain indefinitely in the position in which it isthus placed. As the semi-rings are exactly alike, they areinterchangeable, and their manufacture is rendered simpler than it wouldbe if they were unlike.

I do not limit myself to the precise mechanism shown, as variations maybe made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire tosecure by- Let'- ters Patent is as follows:

1'. As an article of manufacture, a semiringprovided with a male lookingmember at one end and a female locking member at the opposite end, saidmale looking member consisting of a V-spring having the general form ofan arrow head.

2. As an article of manufacture, a semiring provided with an internalarcuate flange and two diametrically opposite spring fingers oblique tothe aXis of the Moreover, by having' semi-ring and integral with saidflange, whereby said semi-ring may be sustained upon a pi p'e'by springcompression of said spring fingers upon said pipe, said semiring beingprovided with a V-spring at one end' having the general form of anarrowhead, and at the other end with a slot.

3; A- fio'o'r: plate consisting of two semirings, each provided with amale locking member at one end" and a female locking memberat theoppositeend, said male looking-- members'consisting of V-spring's havingthe general form of arrow heads;

4; A floor plate consisting of twosemirings, each provided with aninternal arcuate fiange and two diametrically opposite spring fingersoblique to the axis of the semi-rings and integral with said flanges,wherebysaid fingers of each semiring are adapted to impinge a pipe atsubstantially diametrically opposite sides thereof when the parts are'assembled, whereby said semi rings may be" sustained upon a pipe byspring compression of said spring fingers, said" semi rings each beingprovidedwith a V-spring at one end and having "the general form of anarrow head, and at the other end with a slot.
